Merged requested to merge nicoco/slixmpp:fix-xep_0115-static into master
It is unclear to me why, but without
info = await self.caps.get_caps(jid), I had
Coroutine is not subscriptable triggered by
if info and feature in info['features']:.
I also make
StatiCaps.get_caps() async but I am not entirely sure if that is correct.
Maybe I misuse this plugin here.
